MMT Performs Geophysical Soil Investigation of Dutch Wind Farm Zone

Rijksdienst voor Ondernemend Nederland has awarded MMT a contract to perform a geophysical soil investigation of the Ten Noorden van de Waddeneilanden Wind Farm Zone. The objective of the investigation is to contribute to the bathymetrical, morphological and geological understanding of the area. Ultimately the data will be used by offshore wind farm developers to prepare bids for this site. A high-resolution and accuracy ground model ensures that developers can prepare their bids with the least amount of uncertainty, which helps lower the price of developing these OWFs. Project preparations are currently underway, with the fieldwork planned to be performed in July... (read more)

Exploring the Deepest Points on Planet Earth

Report on The Five Deeps Expedition
As extreme explorer Victor Vescovo continues his round-the-world expedition to become the first person to descend to the five deepest points in the Earth’s five oceans using the custom-built deep submergence vehicle Limiting Factor, it prompts the question: ‘Do we know as much about the deepest places on our planet as we thought?’ As extreme explorer Victor Vescovo continues his round-the-world expedition to become the first person to descend to the five deepest points in the Earth’s five oceans using the custom-built deep submergence vehicle Limiting Factor, it prompts the question: ‘Do we know as much about the deepest places on our planet as we thought?’ Today, the best global maps of the oceans have a resolution of 30 arc-second grid cells (926m at the equator). Approximately 82% of the grid cells do not include a single depth measurement (Weatherall et al., 2015), and the percentage of the seafloor that has been directly... (read more)
